Frequently Asked Questions
What is the maximum clock frequency supported by PIC16C74B-04I/L?
The PIC16C74B-04I/L supports a maximum clock frequency of 4 MHz. This makes it suitable for low-to-mid speed embedded control tasks such as sensor reading and relay switching in industrial applications operating from a 2V to 6V supply.
How many ADC channels does PIC16C74B-04I/L provide for analog signal acquisition?
The PIC16C74B-04I/L integrates 8 ADC input channels with 8-bit resolution, allowing direct connection of analog sensors without external converters. This reduces BOM cost significantly in process control or monitoring designs running at up to 4 MHz.
Which package does PIC16C74B-04I/L use and what are its key physical dimensions?
PIC16C74B-04I/L comes in a 44-pin PLCC (Plastic Leaded Chip Carrier) SMT package. This square package measures approximately 17.5 mm x 17.5 mm, simplifying automated PCB placement in space-constrained industrial control boards.
When is PIC16C74B-04I/L preferred over a flash-based PIC16F device?
PIC16C74B-04I/L is preferred in production designs requiring EPROM one-time-programmability for tamper-resistance or regulatory lock-down. The 8-bit core at 4 MHz with 44 pins and on-chip ADC matches legacy system replacements where flash variants would require firmware re-validation.
